Abstract

We sequenced all protein-coding regions of the genome (the "exome") in two family members with combined hypolipidemia, marked by extremely low plasma levels of low-density lipoprotein (LDL) Cholesterol, high-density lipoprotein (HDL) Cholesterol, and triglycerides. These two participants were compound heterozygotes for two distinct nonsense mutations in ANGPTL3 (encoding the angiopoietin-like 3 protein). ANGPTL3 has been reported to inhibit lipoprotein Lipase and endothelial Lipase, thereby increasing plasma triglyceride and HDL Cholesterol levels in rodents. Our finding of ANGPTL3 mutations highlights a role for the gene in LDL Cholesterol metabolism in humans and shows the usefulness of exome sequencing for identification of novel genetic causes of inherited disorders.
